Since 1996, Photonics Trade Group(As PTG) has been a symbol of excellence in high-end NANO materials and Smart Car system, Architectural Lighting in Korea and worldwide. Over half of the korean municipalities, and two hundreds of engineers are already familiar with the PTG brand hallmark, Whose constant message has always been, and continues to be, Innovative technology and technical research & Development, in keeping with eco-friendliness and human sustainability. aSKa Founded by Anderson Kong, engineering, and attentive observer and interpreter of the aesthetic and functional demands of the city, starting from its very heart, PTG`s proposal is twofold : continuity of its calssical style in the Heritage collection and the evolution of its design and function ideals in the contemporary collection. Restoration activities, reproduction, customized luxury maison integration projects, as well as partnerships with architects, lighting designers and energy managers, are just some of the services offered by this aSKa company, which can be found in over 37countries around the world, and that has been a symbol of intelligence and passion for 50years. aSKa believes in the value of people`s dreams. Therefore, our dream should begin with empathy for people`s lives aSKa strives to create a better future with our users. Together, we can contribute to society by creating sustainable values and bring joy and meaning to our lives. This is the design to which aSKa aspires.
Efficiency, thermal management, NANO material tech., glare, NANO Micro optics, selecting materials, lighting quality and connectivity. For aSKa, Research and Development(R&D) means working with determination and consistency on these issues which are crucial for lighting, product development and the sustainability of products. By scientifically investigating these issues it has been possible to design and implement, for example, the performance and comfort product categories : focuses of an ellipse within which LED technology can be experienced and innovated.By independently documenting all aspects of its designs, giving free rein to experimentation and studying with passion and curiosity everything that revolves around lighting, design and urban décor, aSKa has made an international name for itself for both the forms and the substance of its products In the LED field, for example, it has formalized the distinction between performance and comfort: a successful classification which has led to a better understanding and acceptance of light-emitting diode technology in general. The performance aspect, includes products that are more suitable for indoor and mill-works, where the quality of a cold light and maximizing energy savings are priorities. On the comfort side, LED solutions highlight qualities such as the naturalness and harmony of emitted light. In these solutions the aesthetics and the color of light – warmer and less glaring-better combine with the shapes and urbanity of historic centers and with green areas and luxury maison, where they suitably accompany emotions and relationships.
Stressful conditions are created for various elements and the product surface finishes using salt fog, UV-A and humidity cycles. These accelerate the ageing process, and allow technicians to forecast the effects of various factors on the products over time. The high-level technologies used in new products such as LED are also checked here. Innovative laboratories, a distinctive asset of the company, where a dedicated, passionate team of technicians and engineers virtually simulate and exacerbate the environments where the products will be placed, measuring their effects and conduct. This is done using tools that also play a key role in the design phase. These tools are highly sophisticated and even unique in certain respects: as is the case of one of the largest and fastest Gonio photometers in Europe, used for testing the performance of lighting products and their suitability with respect to the restrictive regional regulations on light pollution. In our laboratories, studying and measuring light and matter is what we daily. Their relationship with the environment and future technological developments are constantly associated with the requests coming from outside, and from the markets. Safety tests, such as that performed to determine the degree of resistance to water, solid bodies or powder, and efficiency tests that measure the luminous flux and colorimetric characteristics of the different sources, are elements that provide indispensable added value for the company.
The full-scale reconstruction of a segment of a two-lane road surrounded by night. Light fixtures and sources can change, rotate and move closer to each other, thus allowing us to test and measure the degree of excellence and effectiveness of the products. A”test driver” available to all those wishing to preview the exciting effect of a aSKa product. From laboratory tests on the individual components, to the effects that the assembles, installed products have on the luxury maison, or the mill-works spot lights. This is aSKa`s most impressive and technologically advanced test setting, This is the workplace of lighting designers, engineers, designers, architects, who can measure the potential of every new idea, determining the degree of comfort that might be felt by a motorist or a pedestrian walking alone a hypothetical waterfront. All this is done through a realistic and immersive simulated experience created by a simulator specifically built to meet the company`s innovation and experimentation requirements. It is a valuable component for all of the projects, indeed universities(Chosun Univ.) and technical institutes(KOPTI, KATI) often ask to use it in order to perform very specific tests and simulations, that it would otherwise be impossible to conduct anywhere else in Korea
Architectural Lighting Design is involved in providing specialty lighting design services for the institutional, retail, commercial, industrial and residential markets. Our strengths in innovative and cost effective engineering solutions through design, project management and supervision for installation of energy efficient products and systems. aSKa is committed to continuous quality improvement by adhering to guidelines set forth by the Illuminating Engineering Society of North America (IESNA). and the Client. At Architectural Lighting Design our focus has been to examine, review, select and design lighting systems that enhance the architectural features of a space while creating a comfortable, ergonomic environment for the user. This in turn translates into an optimization of the space and the functions performed in it, within a sustainable basis and within generally accepted environmental constraints. A key issue is to address the interaction between human needs and desires, architecture and aesthetics, economics and budget constraints. In doing so, strive to create a harmonious balance between such considerations as practicality and innovation, rationality and image, consensus and originality. As Lighting Design Specialists we have developed a wide range of lighting design services, from schematic design through to project completion. aSKa applies a collaborative and client-oriented approach to the design process while providing to the most advanced technical means available; this approach supplements the most rigorous engineering perspective with a designer's outlook, inventiveness and sensitivity to a client's needs, and it bridges the gap between the Architect, the Contractor and Sub-Contractors, the Trades, the Engineers and the Client.
This is the NANO Lab workplace of lighting engineers, designers, architects, who can measure the potential of every new innovative idea. All this is done through a realistic and immersive simulated experience created by a simulator specifically built to meet the aSKa`s innovation Program and experimentation requirements. It is a valuable component for all of the projects, indeed universities(Chosun Univ.) and technical institutes(KOPTI, KATI) often ask to use it in order to perform very specific tests and simulations, that it would otherwise be impossible to conduct anywhere else in Korea aSKa Optic-Design provides a complete range of optical design technology.

1- LIGHTING INT. outside the Lamp The light output is typically measured in lumen. A standardized procedure for testing projectors has been established by the American National Standards Institute, which involves averaging together several measurements taken at different positions. ANSI lumen measurements are in general more accurate than the other measurement techniques used in the lighting industry. This allows projectors to be more easily compared on the basis of their output performances. 2- Electric Power of the LAMP The electric power required by an appliance or LAMP. Expressed in Watt. For LAMPS it DOESN’T include the consumption of the DRIVER COMPATIBILITY GUIDE along with the light fixture. 3- Luminous efficacy of the LAMP In lumen per watt, we are considering the efficiency of the driver, and of the optical layer in front of the lamp. This is the ratio between lumens measured in paragraph 1 and the total power of the device, given in paragraph 2. 4- Color Rendering Index(CRI_Ra) CRI means of the CIE 1994 special colour rendering indices for a specified set of test colour samples:  The first eight samples are relatively low saturated colors and are evenly distributed over the complete range of hues. These eight samples are employed to calculate the general color rendering index Ra.  The last six samples provide supplementary information about the color rendering properties of the light source; the first four for high saturation, and the last two as representatives of well-known objects. For luxury retail, please ask for CRI >90 but in some instances, we can find a CRI>90 renders woods too pink, or fabrics too flat.   Ultimately the material should be presented in front of a selection of finishes and materials that could be used for the definitive projects. The eye will be the last tool of appreciation of the rendering. 5- CTA_R9 Value (Color Quality Scale(CQS) CQS is a new metric that includes the 14 colors below + white.  It considers a number of factors in trying to define the way a light source reproduces colour. These include chromatic discrimination, human preference, and color rendering (the method evaluates 15 colors to more accurately span the range of normal object colors). For now, CRI remains the only internationally recognized color rendering system. Whether the lighting industry, especially the solid-state category, will continue to use it for evaluating lighting applications remains to be seen. 6- Correlated Color Temperature(CCT in Kelvin) Color temperatures over 5,000K are called cool colors (blueish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red). This relation, however, is a psychological one in contrast to the physical relation implied by Wien's displacement law, according to which the spectral peak is shifted towards shorter wavelengths (resulting in a more blueish white) for higher temperatures. The color temperature of sunlight above the atmosphere is about 5,900 K.7- Binning and Color Consistency 8- Beam angle/Field Angle 9- Engineering Tilt angle / Pan angle Design10- Beam image PART II : DRIVER COMPATIBILITY GUIDE PERFORMANCES 1- Constant Current Regulation or PWM? 2- Minimum Wattage in sleepmodePART II : DRIVER COMPATIBILITY GUIDE PERFORMANCES 4- Efficiency of the drivers 5- Power Factor = Cosɕ + Total Harmonic Distorsion PART III : TEST ENVIRONMENT
